Jay Z now plans to launch a venture capital fund with business partner and Roc Nation president Jay Brown, reports Axios business editor Dan Primack thanks to a tip from unnamed sources. Primack reported yesterday that Jay Z and Brown are also seeking a full-time investment partner and have partnered with San Francisco-based VC firm Sherpa Capital, which has invested in Uber and Airbnb. They haven’t set a target for the size of the fund.

No one involved has spoken publicly on the issue. The focus is said to be on seed-stage tech opportunities, “with this really being the institutionalization of Jay Z and Jay Brown’s previous angel investing activities,” such as Uber, JetStarter and Tidal, according to Axios.
